2W Threaded 2-Way 2-Position (Normally Open) Solenoid ValveOverview

The 2W series (DN10-DN50) 2/2-way threaded solenoid valve is an industrial-grade automated fluid shut-off valve designed for general fluid processing pipelines. Configured as a normally closed (NC) valve, its operational sequence is "opens when energized, closes when de-energized." The paramount technical attribute of this series is its semi-direct acting (step-by-step direct-acting) structural design, which supports zero differential pressure (0 bar) lightweight startup. By linking the electromagnetic moving plunger directly to the main diaphragm assembly, this valve combines the zero-pressure functionality of direct-acting valves with the high-flow capability of pilot-operated valves. The valve body is constructed from premium brass or high-performance SS316 stainless steel, fitted with standard female pipe threads to accommodate space-restricted and high-rigidity manifold layouts. Powered by heavy-duty electromagnetic coils and precision self-balancing diaphragm components, it performs reliably across a nominal pressure spectrum of 0 to 10 bar and operating temperatures from -20°C to 65°C, delivering remote automated control and tight shut-off for universal fluids.

2W Threaded 2-Way 2-Position (Normally Open) Solenoid ValveCharacteristic

Semi-Direct Acting Mechanism & Zero-Pressure Reliability: Utilizing a linked dual-layer diaphragm layout, it operates effortlessly at zero pressure drop (0 bar) or under gravity-fed conditions without requiring medium pressure assistance, flawlessly eliminating operational failures in low-pressure pipelines.

0 to 10 bar Universal Pressure Spectrum & High Flow Rates: Fluid-dynamics optimized valve cavity and large flow paths significantly enhance the flow coefficient (Kv value), providing extremely low flow resistance and stable isolation under low-to-medium pressure general.

Broad Media Compatibility: Internal sealing Boundaries and diaphragm elastomers are structurally enhanced to perfectly handle frequent control of water, general liquids, gases, and light oils (kinematic viscosity ≤20cst).

Dual Body Configurations (Brass / SS316): Available in high-density brass (cost-effective general-purpose layouts) and precision cast SS316 stainless steel (ideal for light chemical corrosion, high-purity media) to resist harsh environments.

Rigid Threaded Connection with Robust Build: Spanning full sizes from DN10 to DN50, standard pipe threads minimize structural distortion and joint weeping caused by intense mechanical fluid vibrations.
